This article (h/t R.P.) interprets this fact as the influence of closet Islamists in PM Manmohan Singh's cabinet. The other possibility that occurs to me is that since the 1267 committee "takes all its decisions by consensus" and consists of all 15 members of the Security Council (see the link above), the mention of the explicit targeting of the Chabad House was elided to obtain unanimity - after all, the Jamaat-ud-Dawa was proscribed. Among the current members, which are the permanent five - the US, Russia, UK, France and China - and the temporary ten - Belgium, Burkina Faso, Costa Rica, Croatia, Indonesia, Italy, Libya, Panama, South Africa and Vietnam - the primary suspects must then be China, Libya and Indonesia.
